This is just a general question. I know, obviously, that there are RS-232 "serial ports" and IEEE 1284/Centronix ports "parallel ports," and that these are "digital" connections. Then you have things ...

ANSWER: The most obvious difference is size. The parallel port on the back of your computer is a 25-pin port, while the serial port has room for nine pins. But the real difference is in the way they ...

So I'm trying to detect through Visual Basic 6.0 when a voltage change occurs on one of the pins of the serial/parallel port. The whole thing is pretty simple; no data transfer/handshaking/etc needs ...

This application note presents the process of converting a serial output into parallel output using common serial-to-parallel register integrated circuits. The document also discussed the CS556x/7x/8x ...

A socket that connects to a serial interface (one bit following another over one line). Serial ports are widely used by sensors for data acquisition, and they were standard on early computers for ...

If you've been using computers for more than a couple of decades, you've probably used a serial port to attach peripherals like your mouse and modem. Until the USB standard rendered them obsolete in ...

Getting data to a storage medium requires transmission. Parallel transmission has historically been the preferred way to write data to disk. But at current speeds, serial transmission can be faster ...

While the average computer user likely hasn’t given much thought to the lowly serial port in decades, the same can’t be said for the hardware hacker. Cheap serial-to-USB adapters are invaluable for ...
